Because of its low saturation and relatively low brightness, it works well in contrast to bright colors or as a background tone, but might need extra work to improve accessibility.

The hex color #2B1385, also known as Blue Gem, presents several accessibility considerations for web developers. Its dark hue requires careful attention to contrast ratios when used for text or interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text against its background to ensure readability for users with visual impairments. Lighter shades of yellow, orange, or even pale greens and blues would be appropriate choices for foreground text, ensuring that users can easily distinguish the text from the background. Avoid using this color as a background for light or similarly dark text, as the low contrast can make it difficult or impossible to read, thereby excluding users with visual impairments. Thorough testing with accessibility evaluation tools is crucial to validate that color combinations meet the necessary contrast ratios and provide an inclusive user experience. Using this color sparingly, perhaps for decorative elements rather than functional components, can also mitigate potential accessibility issues.
